"What happened?"---Troll comments have _never_ been allowed on this blog and, as I already said, regardless of the content of your current comment, months ago you left a troll comment.

Trolling interferes with useful discussion and so trolls are not allowed.

If you wish to comment, the procedure (as always, since 2009 since the blog began) is to publicly apologize for what you did wrong publicly (so that people know you might be trustworthy and not an Pointless Internet Douche) and then you can comment again.
